We still don't know the story behind these ghoul-like things discovered in Government Center MBTA station

BOSTON - When workers were making repairs to the Blue Line platform as part of the $82 million Government Center overhaul last October, they came across a pair of creepy-looking outfits, complete with masks and a patriotic tinge.

The strange garments were found inside a "small, hollow section of concrete that was poured more than sixty years ago," a spokesman for the MBTA said at the time, adding that the renovations to the station remained on schedule.

The station re-opened, on-budget and on-time, on Monday, but the mystery behind the garments is still very much alive.

"No new information has emerged regarding the costumes/masks that were discovered last October," the spokesman, Joe Pesaturo, said in an email.

An active investigation is "not underway," he added. "But the T welcomes any relevant information someone may have."

The station first opened in 1898, and was then known as "Scollay Square," the same name as the neighborhood. It was the third stop on the oldest subway in the United States, according to the MBTA.

The name changed to "Government Center" when City Hall Plaza was built in the 1960s.

The station, which is a short walk from the Massachusetts State House and steps away from Boston City Hall, closed in 2014 for the renovations.

Workers didn't just find creepy costumes during the overhaul: They also discovered "Scollay Under" mosaics, which were restored and can now be found as riders commute between the Green Line and Blue Line.
